Military communication satellite to be launched on December 19.
- It is a Military communication satellite
- Although all Indian communication satellites offer capacity to the armed forces, GSAT-7A will be the first one built primarily for the Indian Air Force (IAF) to qualitatively unify its assets and improve combined, common intelligence during operations.
- This new space-based dimension adds color to the way the Indian Air Force interlinks, operates and communicates with its aircraft as they fly and with command centres on ground
- This satellite using Ku bandwill enable superior real time aircraft-to-aircraft communication; and between planes that are in flight and their commanders on the ground.
- It will also support aerial activities of the Army and the Navy when required.
- The GSAT-7A incorporates Chemical Propulsion Systemto provide an operational mission life of a minimum of eight years.
- Chemical propulsion will be used for orbit raising as well as for on orbit attitude correction
- Sufficient redundancy is built into the Spacecraft for continued service.
- The Geosynchronous Satellite Launch Vehicle – F11 (GSLV-F11), will undertake its 13th flight carrying the 35th Indian Communication satellite GSAT-7A built by the ISRO.
- It will place the 2,250-kg GSAT-7A communication satellite into a geosynchronous transfer orbit.
GSLV – F11
It is ISRO’s fourth generation launch vehicle with three stages.
- The four liquid strap-ons and a solid rocket motor at the core form the first stage.
- The second stage is equipped with high thrust engine using liquid fuel.
- The Cryogenic Upper Stage forms the third and final stage of the vehicle.
- It would enhance by many times the coveragenow provided by ground communication systems such as radars and stations of the Army.
- Out-of-sight and remote areas where ground infrastructure and signals are difficult would get into the critical information loop.
- The satellite is expected to help the IAF interconnect with various ground radar stations, airbases and AWACS (Airborne Warning And Control System) aircraft.
- Pilots can communicate much better with headquarters while they fly. Headquarters can receive data in real time.
